GridDropDownColumn not populating succeeding rows

[Web team]

When I entered edit mode, rows under my  GridDropDownColumn are not being populated. Img1 shows view mode and img2 shows the edit mode of the Radgrid. Here are the codes:

protected void grdSalesPerson_ItemDataBound(object sender, GridItemEventArgs e)
        {
            if (e.Item is GridEditableItem && (e.Item as GridEditableItem).IsInEditMode)
            {
                GridEditableItem editedItem = e.Item as GridEditableItem;
                GridEditManager editMan = editedItem.EditManager;

                GridDropDownColumnEditor editor = editMan.GetColumnEditor("Manager") as GridDropDownColumnEditor;
                Int64 selectedManagerID = ((User)editedItem.DataItem).ManagerID;

                editor.DataSource = Managers;
                editor.DataTextField = "FullName";
                editor.DataValueField = "UserID";
                editor.DataBind();

                editor.SelectedValue = selectedManagerID.ToString();

            }
        }

:

<MasterTableView EditMode="InPlace" DataKeyNames="UserID">
    <Columns>
        <telerik:GridBoundColumn DataField="FullName" HeaderText="Salesperson"
            UniqueName="FullName" ReadOnly="True">
        </telerik:GridBoundColumn>
        <telerik:GridBoundColumn DataField="Email" HeaderText="Email"
            UniqueName="Email" ReadOnly="True">
        </telerik:GridBoundColumn>
        <telerik:GridDropDownColumn UniqueName="Manager" ListDataMember="Users"
            ListTextField="ManagerFullName" ListValueField="ManagerID"
            HeaderText="Manager" DataField="ManagerID">
        </telerik:GridDropDownColumn>
    </Columns>
</MasterTableView>
    </telerik:RadGrid>

Hi Arnold,

The built-in GridDropDownColumn is designed to be used mainly with DataTables in order to easily map and generate their dropdown items values in conjunction with the DataField/ListValueField/DataSourceID/ListDataMember values of the column.

If you want to bind the data in the grid dropdown editors programmatically, consider replacing the GridDropDownColumn with a template column holding MS DropDownList in its edit template.

For more details refer to this topic from the product help.
